The real sleeper of the Dahlquist line is the dq8 the 8 inch two way it is a lot of speakers for the money in a small to medium sized room and you can get them for not much money but be sure to bring a good high current solid state amp to the party.
Dahlquist speaker models, question/experience and today
Some of us older audio-piles started with Advents, KLH and others...but most of my friends had the Dahlquist DQ-10 at one time in their audio journey. I know nothing about the 9, 20i, 30i etc. If any of you have experience and can compare the DQ-10 vs later models it would be interesting to hear you thoughts/views/experience. Thanks.
